Review for test 1
1. One Sample T- Test Step
A. Ho: M= 40; Ha: does not=40
B. One sample T- Test assume Ho is true, PTOE
C. T(8)= 5.515 p= .001 alpha=.05
44.073< M <49.9210 at the 95 % CI Reject Ho
r2=(t2)/t2+df= (30.415)/ 30.415+8= 0.79= r2
D. Police officers on average work significantly longer than full time duty
officers assuming that full time is M= 40 hours per week.
Steps to a One sample T- Test
Data view, analyze, compare means, one sample t test, move from left to
right, test value= M, add M to lower and Upper CI.
2. Independent Sample T test
A. Ho: M1-M2= 0; Ha: M1-M2 does not = 0
B. Independent Sample T- Test; assume Ho is true; PTOE
C. T(10)= 5.347; p=.000 alpha= .05
8.653< M1-M2<21.013 at the 95% CI we reject Ho
D. There is a significant difference between the group of smokers who
received the treatment with the acupuncture needles and the second
group of smokers who were only given the relaxation instruction with no
acupuncture treatment.
3. Paired Sample T- Test
A. Ho: Md=0 Ha: Md does not= 0
B. Paired sample T Test assume Ho is true PTOE
C. T(6)= 3.361 p=.015 alpha = .05
2.175< Md< 13.824
r2= 0.65
D. There is a significant difference between the # of times the individuals
with agoraphobia left the house before and after the two months of
treatment. After the treatment the average was greater.
